Weathering and Erosion

When rocks are broken down into smaller pieces

• erosion
• weathering
• sediment

When water, ice and wind move particles of rock and soil from one place to another

• sediment
• weathering
• erosion

Look at the two rock samples. Which statement best describes the two rock samples?

• Rock Sample A has undergone severe physical weathering.

  Rock Sample B has undergone severe chemical weathering.

• Rock Sample A has undergone severe chemical weathering.

  Rock Sample B has undergone severe physical weathering.

• Both Rock Sample A and Rock Sample B have undergone severe chemical weathering.

• Both Rock Sample A and Rock Sample B have undergone severe physical weathering.

Susan and Max set up this experiment. Susan stands behind the sand and the rock and blows in the direction of the box. Max measures how much of the sand traveled. Which process is Susan and Max most likely acting out?

• water erosion

• chemical weathering

• physical weathering

• wind erosion

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place
• makes the rocks last longer
• expands cracks and breaks rocks
• causes rocks to fall in landslides

Look at the picture of an experiment set up by Juanita and Ben.

They keep the limestone samples in the liquids overnight. The next morning, they put a strainer on top of each beaker and pour the liquid into a pan. Which statement best describes the results of the experiment

• The strainer over the water would have more particles left in it than the strainer over the weak acid.

• The strainer over the weak acid would have more particles left in it than the strainer over the water.

• Both strainers would have about the same amount of particles in them

• Both strainers would have no particles in them.
